- Description
- An ICO file is an image format used to store icons for Windows programs, files, and folders. It contains two bitmaps: 1) the AND bitmap - the image mask (which determines what part of the icon is transparent) and 2) the XOR bitmap - contains the icon which is mapped onto the image mask. ICO files can be modified to create custom icons.
- The Sun Rasterfile, identified by the extension .rast, is a bitmap image file format originally developed for use on SunOS by Sun Microsystems. It is designed to store color and monochromatic raster images, such as scanned photographs and digital artwork. The format supports various color depths, including 1, 8, 24, and 32 bits per pixel, allowing for a range of color representations from simple black and white to full true color images. Despite its origins on Sun systems, the format can be used on various platforms and is supported by a variety of image editing and viewing software.
